Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a fruit packaging tray, and more specifically, it protects a substantially spherical fruit such as an apple or a pear from an impact and allows it to be safely transported or stored. The present invention relates to a fruit packaging tray useful for.

<Prior Art and Problems to be Solved by the Invention> Conventionally, as the fruit transportation package, a tray made of expanded polystyrene resin sheet having a large number of substantially hemispherical recesses adapted to the shape of fruit has been used. Has been. The tray has the convenience of being able to efficiently store fruits in a large number of recesses in order, but the recesses are arranged in order in the vertical, horizontal, or diagonal directions.

On the other hand, the fruit packaging tray is one in which after storing fruits, the trays are stacked and stored in a corrugated cardboard box in multiple stages, so the size of the tray matches the inner size of the corrugated cardboard box conforming to the standard. The size will be regulated. The number of fruits stored in a tray regulated to a certain size will vary depending on the size of the fruits, and the number of recesses will be formed in the tray according to the size of the fruits stored. Will be done.

However, in a conventional tray in which a plurality of recesses are arranged in order in the vertical and horizontal directions or diagonally, many surplus parts are generated between the recesses, which is not good in terms of storage efficiency. For this reason, conventionally, 16 holes having a large number of recessed portions,
In the case of 18 holes, you can shift the adjacent recesses,
It is provided in an attempt to increase the desired storage efficiency by staggering the rows alternately. However, trays having a larger number of recesses are difficult to arrange because of the large number of trays, which impairs the storage balance. Further, in this type of tray, the directionality thereof is one important issue, and it is preferable that the trays can be stacked in reverse by changing the direction by 180 °, for example.

This invention has been made in view of the above problems.
It is an object of the present invention to provide a fruit packaging tray which can store six fruits in a well-balanced manner and is easy to use.

<Means for Solving the Problems> A fruit packaging tray of the present invention for achieving the above object is a rectangular tray that stores 26 fruits, and has a long side (L) (facing) facing each other. 6 recesses along L ')
(1) (2) (3) (4) (5) (6) and (7) (8) (9) (10) (11) (12) is formed, the short side (S) (S ′) Each row along
Recesses (13), (14), (15), (1) close to (1), (7), (6), (12)
6) and recesses (17) and (18) that are close to each other in the center of the tray between the recesses (3) and (4) and between (9) and (10).
(2) (3) (4) (5) (6) (13) (15) (17) concave (7) (8) (9)
(10) (11) (12) (14) (16) (18) are provided symmetrically around the center of the tray, and are arranged in a substantially rhombic shape with the recesses (17) (18) as boundaries. 4 recesses (19) (20) (21) (2
2) and (23) (24) (25) (26) are provided symmetrically.

<Operation> According to the fruit packaging tray having the above-described configuration, the concave portions 26 can be arranged with good directionality.

<Embodiment> Next, an embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a plan view of a fruit packaging tray according to an embodiment of the present invention.

In FIG. 1, (A) is a rectangular tray that can store 26 fruits in a substantially spherical shape, and has long sides facing each other.
In each row along (L) (L '), there are six recesses (1) (2) (3) (4) (5) (6), which are recessed and formed in a substantially hemispherical shape. And (7)
(8) (9) (10) (11) (12) are formed (Fig. 2 and 3
See figure).

In each row along the short sides (S) (S '), the recesses (13) and the recesses which are separated from each other on the short side (S) side and close to the recesses (1).
A concave portion (14) close to (7) is formed. Further, a concave portion (15) which is separated from each other on the short side (S ′) side and is close to the concave portion (6) and a concave portion (16) which is close to the concave portion (12) are formed. And, the recessed portion (17) and the recessed portion (9) which are separated from each other at the center of the tray and are close to the side between the recessed portions (3) and (4).
(10) A recess (18) is formed close to the space between them.

In this case, the recesses (1) (2) (3) (4) (5) (6) (13) (15) to the recesses (7) (8) (9) (10) (11) ( 12), (14) and (16) are provided symmetrically around the center of the tray. And the recess (17)
On the other hand, concave portions (18) are also provided symmetrically around the center of the tray.

On the other hand, recesses (1) (2) (3) (7) (8) (9) (13) (14) (17) (18) and recesses (4) (5) (6) (10) The parts surrounded by (11) (12) (15) (16) (17) (18), that is, the parts bordering the recesses (17) (18), are arranged in a substantially rhombic shape. Individual recesses (19) (20) (21) (2
2) and (23) (24) (25) (26) are provided symmetrically.

Therefore, in the fruit packaging tray having the above structure, the 26 recesses are provided in a specific arrangement, that is, the recesses (1) (2) (3) (4) (5). (6) (13) (15) and (7) (8)
(9) (10) (11) (12) (14) (16), recesses (17) and (18), recesses
(19) (20) (21) (22) and (23) (24) (25) (26) are provided symmetrically with respect to each other with respect to the center of the tray, so that the tray storage balance is improved. On the other hand, the arrangement of the above-mentioned recesses has the same shape even if the long sides (L) and (L ') are used in reverse, and it can be used by changing the direction by 180 °, and the tray can be handled. The direction of can be improved.

The tray (A) is housed by being inscribed in a cardboard box conforming to the standard, and a groove-shaped reinforcing portion (40) protruding to the back surface is provided between the predetermined recessed portions on the upper surface of the tray (A). The reinforcing part (40) is formed so as to maintain the rigidity of the tray (A) (see FIG. 4).

Further, as shown in FIG. 3, groove-shaped reinforcing ribs (30) are formed on the bowl-shaped peripheral wall portion of each recess. The reinforcing ribs (30) are formed so as to project outward (back side) and have both functions of ventilation and reinforcement. Also, reinforcing ribs (30)
As described above, instead of the groove-like one projecting outward (back surface) as described above, a projecting ridge projecting inward (front surface) may be formed.

As the thermoplastic resin sheet that is the material of the tray,
A foamed sheet obtained by adding a foaming agent to polystyrene or a copolymer of styrene containing 50% by weight or more of styrene and a monomer copolymerizable with styrene, or a mixed resin of polystyrene and another polymer, and extruding Used for. For example, a foamed sheet of a resin obtained by copolymerizing or mixing a polyolefin resin such as polyethylene, polypropylene, or polybutadiene with polystyrene has excellent flexibility and elasticity, and thus is particularly suitable as a material for the fruit packaging tray of the present invention. . Besides, polyvinyl chloride or other thermoplastic resin sheets can also be used.

The fruit packaging tray of the present invention can be easily obtained by pressing or vacuum forming the thermoplastic resin sheet using a mold having a predetermined shape.

<Effect of Device> As described above, according to the fruit packaging tray of the present invention, since the 26 concave portions are provided in a specific arrangement, the long sides (L) and (L ′) are reversed. The same shape can be used to improve tray storage balance while
The direction of the tray can be changed by 80 °, the directionality of the tray at the time of handling can be improved, and the various usability of the tray can be improved.
